The object of the study was the snow cover in the 30 km zone of influence of the electrometallurgical plant LLC NLMK-Kaluga. As a result of the research, the polyelement composition of the solid fraction, dust load, influx of heavy metals (Fe, Cr, Zn Mn, Ni, Co, Pb, Cu, Cd), concentration factors and total indicators of contamination with heavy metals, as well as the cationic and anionic composition of thawed snow cover waters. It has been established that the intensity of snow cover pollution depends on the direction and distance from the source of pollution. The maximum effect of technogenic impact up to 8 times relative to background values was observed in the near 2 km zone. With increasing distance to 16 km, the dust load decreases and does not exceed 1.5 times. According to the research results, factors influencing the intensity of snow cover pollution have been established.
